Bioregulator peptides are one of the most distinctive categories in modern peptide research, yet they remain far less understood than popular single peptides. This guide introduces what they are, where they came from, and why researchers group them separately.
A brief history
Bioregulator peptides — often called “Khavinson peptides” — trace back to research led by Professor Vladimir Khavinson in Russia from the 1970s onward. The work focused on short peptide chains isolated from tissues, and the concept that specific peptides may be associated with specific tissue types.
What makes them different?
Unlike growth-hormone-related peptides that act broadly on the GH axis, bioregulators are studied as short, tissue-specific peptide sequences. In research literature they are frequently grouped by the tissue they were originally derived from or associated with.
The bioregulator range at a glance
Commonly studied bioregulators include:
- Epitalon — the most well-known, associated in research with the pineal system and telomere-related studies.
- Cortagen — studied in a neurological research context.
- Cartalax — associated with connective/cartilage tissue research.
- Bronchogen — associated with respiratory tissue research.
- Cardiogen — associated with cardiac tissue research.
- Crystagen — studied in an immune-system research context.
Each is a short peptide, typically supplied lyophilised (freeze-dried) for stability during storage and transport.
Why researchers study them as a group
The appeal of the bioregulator category is its organ-specific framing — the hypothesis that different short peptides correspond to different tissues. This makes them a self-contained field of study rather than isolated compounds, which is why laboratories often reference them collectively.
Handling and storage
Like most research peptides, bioregulators are sensitive to heat, light and moisture. They are generally supplied lyophilised and stored cold until reconstitution. See our related guides on lyophilised peptides and bacteriostatic vs sterile water for more on correct handling.
Summary
Bioregulator peptides represent a unique, historically rich corner of peptide research defined by short, tissue-specific sequences. Whether your interest is Epitalon or the wider Khavinson range, understanding the category as a whole provides useful context for any research programme.
